Answer:
The absolute error of the measurement is 0.25 inches
Step-by-step explanation:
we know that
The absolute error of a measurement is equal to one half the unit of measure.
In this problem we have
7.5 inches
The measurement is given by 0.5 inches
So
the absolute error of this measurement is
Therefore
the exact measurement could be between
7.5 (+/-) 0.25 in
That is, between 7.25 in and 7.75 in
Yes yes rhombus, i checked on google
C. Neither..............................................
I just need points so pretend i answered sorry tho hope you find help
Answer:
.
Step-by-step explanation:
Since vertices lie on y-axis. So, it is a vertical parabola of the form
where, (h,k) is center, is focus and is vertex.
Center is (0,0). So, h=0 and k=0.
Foci are . So .
Vertices are . So .
We know that,
Put h=0,k=0, a=8 and b=3 in equation (1).
Therefore, the required equation is
.
